To all 'whom it may concern:

Be it known that l, RICHARD V. MATTISON, Jr., a citizenof the United States, residing in Upper Dublin township, in the county of rMontgomery and State of Pennsylvania.,l

have invented certain new and use ful Improvements in Mechanism for Applying Dry Color to Asbestos-Cement Sheets, whereof divided into sections in the form of tiles l,

According to my inventlon I provide means forcarrying the asbestos ce-` or shingles.

ment sheets beneath a rotary brush by which the color is applied. The dry coloringv maty ter is fed to this brush by means which aditi mit of accurate control of the rate of supply. A `second rotary brush turning in the direction opposed to that of the first mentioned one completesy the even distribution of the coloring matter upon the surface y of the asbestos cement sheets. A

lln the accompanying drawings, l have illustrated an embodiment of my invention in. which Figure 1 is a longitudinal sectional view of the mechanism. v

llig. lll is an.elevation showing certain parts incross section along the line lll, lill, of Fig.. ll. v

The asbestos cement sheets are fed as b v an apron 1, and bridge 2, to an endless carrying apron 3, running upon and driven by the roller 4. Support is given to the apron 3, sufficient to enable it to hold its load of asbestos cement sheets by means of the plate 5, immediately below the upper half of the traveling aproh and the apron. is hept taut by an idler roll 6, pivoted upon the swinging arms "I, so that its weight depends upon the lower or return half of the traveling apron.

The rotary coloring brush 8, is-mounted between the housings 9, which are erected one on either side of the traveling apron. A similarrotary coloring brush 1G, is likewise mounted betweei'rthe housings 9, in succession to the brush 8.

llhe brush 10, is driven bya sprocket drive 11, so as to rotate asindicated by the arrow in opposition to the travel of the apron.

The brush 8, is geared to brush 10, by the companion gears 18, and 19, by which said brush 8, is causedfto'rotate in correspondence with the travel of the apron and at a more rapid speed than brush 10. The bristles' of the brush 10, are preferably longer than those of brush 8.

.Dry lcoloring matter is continuously fed in regular quantities to the top of the brush 8, from the color reservoir` 12. The lower end of this color reservoir has a slotted aperture within which rotates, itting with precision, the channeled cylinder 13. On the feed side thesurface of this channeled roller is protected by the plate or overhang 14, formed 'upon the lower side of the color reservoir. The parts which have just been described are supported by the housings 9', and immediately superimposed upon the rotary color brush 8, so that as the channeled roller 13, rotates, the dry coloring matter received within its channels is car- ,rie'd down to anddischargedupon the upper surface of ysaid brush and by it carried verse direction.

1t is important that the rate `at which the dry coloring matter is fed'to the asbestos cement sheets yshould be accurately regulated, otherwise satisfactory results cannot be obtained. To this end the slot in the bottom of the color reservoir 12, which runs the channeled cylinder'l, is provided at either end with segmental shutters 15, which can be moved toward or away from each other, in such a way as to uncover more or less of the grooved surface of the underlying cylinder so as to regulate the amount of dry coloring matter discharged through the bottom of the color reservoir. These shutters arehinged as at 16, and are moved by a handle 17, set upon the projecting end of their pivots. The rate of b supply of the coloring matter is further dependent upon the speed with which the' within Mit grooved cylinder v13, rotates and this is regu- .lated as follows: Said grooved cylinder is driven by a worm gear 20, driven by a worm 21, on the shaft 22, upon which is splined the shaft 23, movable longitudinally' therevfrom which said grooved cylinderderives its motion, the rate of speed depending upon the adjustment between the disks 23. and 24,

which can be regulated at the |will of they operator. By means ofV such regulation in combination with the additional regulation obtained by varying the position of the shutters l5, i secure a very accurate determination of the exact quantity of coloringi matter fed to the brush ,and therefore applied to the' upper surface of-the asbestos cement sheets, as they travel beneath the brushes.

Having vthus described my invention, l claim l. In a device of the class described, the combination of a color reservoir; an aper` ture in the base thereof; a grooved cylinder rotating;q in said aperture; a rotary color brush rotating below said grooved cylinder; means for carrying surfaces to be colored in contact with said rotary brush; and means for regulating the speed with which` the grooved cylinder rotates.

2. ln' a device of the class described, the combination of two color brushes rotating in opposite directions; means for con'tinu-- tatingwithin said aperture, andhaving the lower side of its perimeter so closely related to the lirst of the rotary color brushes as to deposit upon said brush the coloring matter which' said grooves receive as they pass through the reservoir.

3. In mechanism for applying* dry color Y 'the first to act on lthe sheet material and the coloringr matter is supplied to it and by it supplied upon the sheet material.

5. ln mechanism for applying color to moving surfaces, the combination of means for effecting continuous travel of said surfaces to be colored; two successive color brushes rotating in contact with said moving surfaces, the iirst of -said brushes having its ,contacting surface moving in the same direction asthe surface to be colored, but more rapidly than it, the second of said brushes rotating less rapidly than the first and inthe opposite direction; and means for supplying coloring* matter to the rst of said brushes. y

, ln testimony whereof l have hereunto signed my name at Philadelphia, Pennsy1 Vania, this tenth day of February, 1919.
